  • CLINICAL APPLICATION OF MICRO TRANSVERSE FLAP PEDICLED WITH SUPERFICIAL PALMAR BRANCH OF RADIAL ARTERY FROM PALMAR WRIST TO REPAIR SKIN DEFECT OF FINGER

    Objective To investigate the clinical application of micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist to repair skin defect of finger. Methods Twenty-six cases (26 fingers) with skin defect of finger were repaired with micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist between December 2011 and February 2013. There were 20 males and 6 females with the average age of 31.5 years (range, 20-56 years). The causes of injury included cutting injury in 20 cases and crushing injury in 6 cases. The time from injury to admission was 1-5 hours with an average of 2 hours. Injured fingers included thumb in 6 cases, index finger in 6 cases, middle finger in 6 cases, ring finger in 4 cases, and little finger in 4 cases; the locations were the dorsal side of the finger in 6 cases, lateral side in 6 cases, and the volar of the finger tip in 14 cases; there were 4 cases on the proximal phalangeal skin, 8 cases on the middle phalangeal skin, and 14 cases on the distal phalangeal skin. The defect area ranged from 2.0 cm × 1.5 cm to 4.0 cm × 2.0 cm, and the flap area ranged from 2.5 cm × 2.0 cm to 4.5 cm × 2.5 cm. All the donor sites were directly sutured. Results The flaps of 25 cases survived well after operation, and wound healed by first intention; 1 case had partial necrosis and the wound had a scar healing by changing dressing. All cases were followed up 6-12 months (mean, 10 months). The color and appearance of the flaps were satisfactory with tender texture. The two-point discrimination of the flap was 5-8 mm (mean, 6.8 mm). The donor sites healed primarily without scar contracture and limitation of wrist flexion or extension. Conclusion The micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist is a good option to repair skin defect of finger. It has the advantages of hidden donor site, the same operative field, great comparability of flap and finger skin, and it can be used as a vascularized tendon or nerve graft.

  • DIAGNOSE AND TREATMENT OF INTRA-ARTICULAR FRACTURE OF FIFTH METACARPALE BASE WITH CARPOMETACARPAL JOINT DISLOCATION

    Objective To investigate the diagnose and treatment of intra-articular fracture of the 5th metacarpale base with carpometacarpal joint dislocation (reverse Bennett fracture). Methods Between January 2008 and March 2012, 26 cases of reverse Bennett fracture were treated. There were 20 males and 6 females, aged 19-48 years (mean, 26 years). The injury causes included boxing injury in 19 cases, falling injury in 3 cases, heavy pound injury in 3 cases, and crushing injury in 1 case. According to Lundeen classification, there were 8 cases of type A, 9 cases of type B, 3 cases of type C, and 6 cases of type D. The time from injury to operation ranged 1-8 days with an average of 4 days. All patients underwent open reduction and internal fixation with Kirschner wires, screws, or plates by L-shaped dorsal incision. Results Primary healing was obtained in all incisions; no infection, hematoma, and necrosis occurred after operation. All patients were followed up with an average time of 12.5 months (range, 8-24 months). X-ray films showed that all fractures healed after 6-8 weeks (mean, 6.5 weeks); no delayed union or nonunion and no the 5th carpometacarpal joint dislocation were observed. Two cases had mild osteoarthritis. According to the upper extremity functional evaluation standard by Hand Surgery Branch of Chinese Medical Association, the results were excellent in 22 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate of 96.2%. Conclusion For patients with reverse Bennett fracture, good results can be obtained if early diagnose is done and appropriate internal fixation is selected.

  • DECOMPRESSION AND ANTERIOR TRANSPOSITION OF ULNAR NERVE WITH INFERIOR ULNARCOLLATERAL ARTERY FOR CUBITAL TUNNEL SYNDROME

    Objective To report the operation method and the cl inical effect of decompression and anterior transposition of the ulnar nerve with inferior ulnar collateral artery for cubital tunnel syndrome. Methods From September 2005 to May 2006, 25 cases of cubital tunnel syndrome were treated by the method of decompression and anterior transposition of the ulnar nerve with inferior ulnar collateral artery. There were 19 males and 6 females with an average of 60 years (20-72 years). The disease course was 2 months to 3 years (mean 6.7 months). The causes were ostesarthritis in 23 cases, cubital tunnel cyst in 1 case and ulnar nerve ol isthy in 1 case. According to Pasque grading system for cubital tunnel syndrome, 19 cases were graded as good and 6 cases were graded as poor. Electrophysiological examination showed the motor nerve conduction velocity of the ulnar nerve around the elbow joint was less than 42 m/s. Results All wounds healed by first intention and no operative compl ications and recurrences occurred. All patients were followed up for one year to two and half years (13.9 months on average). According to Pasque grading system for cubital tunnel syndrome, 15 cases were graded as excellent, 9 cases as good and 1 case as fair. The excellent and good rate was 96%, indicating a significant difference compared with the results before operation (P lt; 0.05). Electrophysiological examination showed the motor nerve conduction velocity of the ulnar nerve around the elbow joint was more than 42 m/s. Conclusion The method of decompression and anterior transposition of the ulnar nerve with inferior ulnar collateral artery is safe and effective for the treatment of cubital tunnel syndrome.

  • Application of radial-lateral forearm free perforator flap on repairing of soft tissue defects in finger

    ObjectiveTo investigate the effectiveness of radial-lateral forearm free perforator flap on repairing of soft tissue defects in the finger.MethodsBetween January 2017 and May 2018, 26 cases of finger skin defects were treated with radial-lateral forearm free perforator flap based on the radial branch of the posterior interosseus artery. There were 21 males and 5 females, with an average age of 26.6 years (range, 19-56 years). The cause of injury included the cutting injury in 16 cases and crush injury in 10 cases. The interval between injury and admission was 30 minutes to 4 hours (mean, 1.5 hours). The injury located at thumb in 6 cases, index finger in 8 cases, middle finger in 6 cases, ring finger in 3 cases, and little finger in 3 cases; and at the dorsum of finger in 6 cases, the lateral side in 6 cases, and the palm in 14 cases. All wounds were accompanied with the tendon and bone exposures, and phalangeal fractures occurred in 10 cases. The size of the defects ranged from 2.0 cm×1.0 cm to 4.0 cm×2.5 cm. And the size of the flap ranged from 2.5 cm×1.5 cm to 4.5 cm×3.0 cm. All wounds at donor sites were sutured directly.ResultsAll the 26 cases were followed up 4-12 months (mean, 7 months). The 24 flaps survived uneventfully after operation, and the wounds healed by first intention. Partial necrosis occurred at the distal part in 2 flaps, and secondary healing achieved after debridement and dressing. All incisions at donor sites healed by first intention. The appearance and texture of all flaps were satisfactory. The two-point discrimination of the flaps was 5-10 mm (mean, 8 mm) at 4 months after operation. Sensory of the flaps was grade S3. Only linear scar was noted at the donor site.ConclusionThe radial-lateral forearm free perforator flap in repairing of the soft tissues in finger can shorten the disease duration, reduce the damage of the donor site, and improve the patients’ quality of life.
